Julius N. Y. l Applictio: my@ 730,158 v This invention appertains to new and useful improvements in fuel vaporizers,.and more pari i6 In the drawings:

Figure 1 represents an end elevational view of the device in accordance with the present invention.

Figure 2 represents a longitudinall sectional 20 view through the mixing chamber. Y

Figure 3 represents a horizontal sectional view l through the mixing chamber.

Figure 4 represents a vertical sectional view through the air pump. 25 Figure 5 represents a sectional view taken substantially on line 5--5 of Figure 3. d

Referring to the drawings .wherein like numerals designate like parts, it can be seen thatnumeral 5 represents a float chamber, while nu- 30 meral 6 represents the induction tube or mixing chamber of the vaporizer, the same being provided with a ange 'I at one end, whereby the tube can be attached to tige usual intake manifold. Reference numerals 8 and 8e denote valves 35 conventionally known as the choke and damper throttle which are rockably mounted in the induction tube 6. The tube, as is clearly shown in Figures 2 and 3, 'is provided with an elongated opening 9 in the wall thereof. 40 Numeral ill represents a block which is suitably secured to the outer side of the tube 6 over the opening 9 and also suitably secured to the float chamber 5. This block I0 is provided with an elongated passageway Il therein communil,45 eating at one end lwith the upstanding jet I2,

while its opposite end is internally threaded to receive the plug i3. At this end of the passage- A way Il, the block I0 is provided with an upstanding neck I4 having a laterally disposed jet 50 l5 which is adapted to ow across the tip of the fuel jet I6, these jets being arranged in substantially the manner yshown clearly in Figure 3.

Reference numeral l1 denotes -a `compressed air pump havingits inlet at LIB and the conduit 55 pipe I s extending therefrom to connect to the block lIt and commlmicate with the passageway II, as at 20. Numeral 2| represents a baille which is maintained spaced from the side portions of the tube E by the offset end portion 22 which is suitably 5 secured to the side portions of the tube v8. This baille serves to prevent heavy vapor from passing out of the tube 6. Any condensation is'col lected in the pocket 23, which is provided with a clean-out plug 2| and from this pocket, the 1o liquid fuel can return to the oat'chamber by way of the conduit duet 28. (See Figure 3.) A conduit duct 21 also extends through the supporting arm 28 of the oat chamber 5 and opens through the wall of the tube 6 at a point out- 15 wardly of the butterily valve 8.

lIt can now be seen that in operation, let it be assumed that the motor 29 of the compressor or y pump I1 is in circuit with the usual ignition switch of the automobile. When the switch is turned on, the motor 29 will become energized and drive the pump Il. Compressed air will now be supplied to the passageway II and will spray into the tube 6. Compressed air from the jet i5 in passing over the jet I6, will break up the fuel issuing from the jet I 6 and thoroughly mix the same, while a second treatment of the fuel vapor is performed by thejet i2 spraying compressed air transversely of the tube B, thus insuring complete mixing of the fuel vapor before it passes to 30 the outlet end of the -tube 6.

'While the foregoing specication sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described thevinvention. what is claimed as new isf- 1. A fuel vaporizer comprising a float chamber, 40 a single air induction tube constituting a mixing chamber having one ,end open and the other end adapted for connection to an intake manifold of an internal combustion engine, a throttle valve and a choke valve mounted in the tube and' 45 axially spaced from each other to provide a vaporizing compartment in an intermediate portion of the tube. a fuel conductor leading from the float chamber and terminating in the vaporliaing compartment in a fuel jet discharging a fue] stream at right angles to the axis of the tube,4 one 1 of the air nozzles discharging air under pressure 2. A fuel vaporizer comprising a ioat chamber.

a single air induction tube constituting a mixing chamber having one end open and the other end adapted for connection to an intake manifold of an internal combustion engine, a throttle valve spaced from eachother to provide a vaporizing compartment of substantially the same diameter as'the tube, a fuel conductor leading from the v float chamber and terminating in the vaporizing .compartment in a fuel jet discharging a .fuel

stream at right angles to the axis of the tube, a

pair of air nozzles one to each side of the fuel jet, one of the air nozzles discharging air under pressure` at the mouth of the' fuell jet at right angles tothe fuel stream and the other of said air nozzles discharging lair under pressure at right angles to the air stream discharged by the rst mentioned air nozzle, and a baille in the vaporizing compartment, said tube being formed with a passage adjacent to'the baie and connected with the oat chamber for conducting 'condensed fuel back into the float chamber. Y

3. A fuel vaporizer comprising a single elont gated air induction casing constituting a mixing chamber having one open end and the other end adapted for connection to an intake manifold of an internal combustion engine,Y a throttle valve and a choke valve mounted in the casing and longitudinally spaced from each other to the vaporizing compartment.

provide a vaporizing compartment within the confines of the induction casing, -a fuel jet and a pair of air nozzles'all within the vaporizing compartment, one of said nozzles directed at the mouth of the fuel jet to produce a Venturi eect 5 on the fuel jet, and the other ofsaid nozzles di- @rected at an angle to the air stream of the first and a choke valve mounted in the tube and'axially mentioned nozzle .to thoroughly mix the charge.

4. A fuel vaporizer comprising a float chamber, an air induction casing constituting a mix- 10 ing chamber having one end open and the other end adapted for connection to an intake manifold of an internal combustion engine, a throttle valve and a choke valve mounted in the casing in spaced relationto each other to provide a va- 15 porizing compartment within the coniines of the induction casing, a fuel jet and a pair of air nozzles all within the vaporizing compartment, one of said nozzles directed at the mouth of the fuel jet, the other of said nozzles directed at an'angle 20 to the air stream of the rst mentioned nozzle, a baie in the vaporizing compartment, said casing formed with a passage adjacent to the baiiieand connected with the oat chamber for conclucting condensed fuel back into the oat chamber, 25

and said casing formed with another passageA connected with the float chamber at. one end and registering at the other end with the mixing chamber between the open end of the casing and JULIU S DANIEL BASI-IOR.
